This species, the Perca marina of Linnaeus, frequents high latitudes, and is little known as a native of our own seas, excepting along the northern coasts of the Island. Has been met with on the coasts of Aberdeenshire and Berwickshire; also in Zetland by Dr. Fleming. Food, according to Cuvier, Crustacea and small fish. Obs. It is very doubtful whether the Sea-Perch of Willughby * be referable to this species.
